Methods and systems for providing a virtual private network service on a per mobile application basis are presented. In some embodiments, a mobile device that is connected to private network may determine that one of its mobile applications is requesting to communicate with a private network. The mobile device may intercept one or more system calls to communicate with the private network issued by the mobile application. The mobile device may generate a communication link to a virtual private network (VPN) server on a port of the mobile device through which to transmit communications from the mobile application to the private network. The mobile device may instruct the VPN server to transmit one or more messages from the mobile application to an access gateway for forwarding to the private network.
